With OrthoPilot®, physicians have a tool for the precise execution of surgical interventions. The essential criterion in the development of the OrthoPilot® was its perfect integration within the surgical workflow by avoiding extension of operating time. In parallel, minimizing the strain on the patient caused by the navigation procedures was a central issue. OrthoPilot® was developed to achieve the main surgical goal of perfect implant alignment without having to perform preoperational examinations or take radiation-intensive and expensive CT or MRI scans.
